De Meirleir told me that IL-8 is often elevated in CFS/ME. Others have observed the same. This study indicates the opposite.

Thats strange, perhaps IL-8 is not best cytokine to look at. In this study IL-8 has a fairly high spread so if the number of tested persons are low one could end up with the opposit result by chance.
